City of Kwinana collects 815 pounds of garbage using drainage nets.
The city of Kwinana is testing a simple, yet cost-effective solution to reduce the discharge of waste from drainage systems.
The Western Australian town installed nets on the outlet of drainage pipes, preventing solid waste and gross pollutants from leaving the sewers.
The goal is to prevent solid residues of average dimensions that come from residential zones and are transported by rain waters from contaminating the Henley Reserve.
The simple filtering system started working in March at two locations, near residential areas and have, since then, retained 815 pounds (370 kilograms) of garbage.
The nets have collected mostly food packaging, bottles, sand, and leaves from trees. The debris is later transported to a recycling center which processes biodegradable waste and turns it into fertilizer.
The nets were installed on 750mm and 450mm-diameter concrete drainage pipe outlets, and have been cleaned three times since March. No animal has been trapped inside the nets since the trial operation began.
